oh for sure, however, the cobra engine is built, it has a forged crank good for 1500hp, manley h beam rods, and a solid iron block. Basically it has already been built, and to properly build a 3v 5.4l you would spend much more than 6k. With simple exhaust and a pulley on the eaton you will pick up 100 additional HP.
blower 5k, good heads 2k min, a set of cams up to 1k, and you still have a stock bottom end that was never built for boost.
